Well, I realize that this has been answered to death, but heres a solution along a very different line, which also offers some extra flexibility.

#!/usr/local/bin/perl -w
use strict;
use Tie::Cycle;

$\=$/;
my @a=qw(want vegas every first night third array my element);

tie my $ok,'Tie::Cycle',[0,0,1];
$ok && print $_ foreach @a;

The flexibility of this approach can be seen by changing [0,0,1] to [1,0,1].

Of course I'm not really sure why anyone would _want_ to do anything like this, but you never know what'll come up...
